Mactra stultorum, previously sometimes known as Mactra corallina, is a species of edible saltwater clam, a marine bivalve mollusc in the family Mactridae, the trough shells.
Distribution
[edit]This species lives in the Black Sea, the Mediterranean coasts, and the west coast of Europe, from Norway to the Iberian Peninsula, and south to Senegal.
Habitat
[edit]This bivalve lives on sandy (rarely soft) bottoms at depths of between 5 and 30 m, although the shell is very often found on beaches, where it has been cast up by wave action.
Shell description
[edit]This species has a very thin and delicate shell, which has concentric growth lines and sometimes also has colored radiating bands, hence its common name, the rayed trough shell. The shell interior is white.
